I've never done a super restrictive resolution game before -- but have done plenty of "retro" pixel art stuff. I've seen a handful of games that take the "low rez 3D" angle and frankly, it's super cool.
I'm not terribly great at this game, so I didn't beat it. I managed to find a pentagram that led to a fight that completely destroyed me.
I'll be playing this game more in an attempt to finish it. I really had fun with it. The secrets were satisfying to find, for sure. Melee felt a little awkward, but the gunplay felt surprisingly good for the limitation. Very well done.
